StackOverFlow in Form Editor [message #480325]

Hello. I'm trying RAP - new to it. I made a Class which is a form editor
and made an editor page. I get a weird StackOverFlow when I open the
editor.

I'm probably missing something which causes this recurrence but since none
of my code is touched, per the stack trace, I'm not sure what I'm doing
wrong.

Here is the stack trace and what I think is the relevant code.

Here is the key code:

public class TranslationEditor extends FormEditor

protected void addPages ()
{
try {
translationEditorPage = new TranslationEditorPage (this);
addPage (translationEditorPage, getEditorInput());
}
catch (PartInitException myPartInitException) {
myPartInitException.printStackTrace ();
}
}

public class TranslationEditorPage extends FormPage
public void createFormContent (
IManagedForm aManagedForm
)
{

FormToolkit myToolkit = aManagedForm.getToolkit ();
ScrolledForm myScrolledForm = aManagedForm.getForm ();
myScrolledForm.setText (

objectToTranslate.getIdentifier ()
+ " ["
+
objectToTranslate.getTranslationLocale ()
+ "]"
);
setPartName (myScrolledForm.getText ());
myToolkit.decorateFormHeading (myScrolledForm.getForm ());

}

public class OpenObjectTranslationEditorAction extends Action
implements ISelectionListener
public void run ()
{
if (selection == null || isEnabled () == false) {
return;
}
else {
try {
TranslationEditorInput myEditorInput = new
TranslationEditorInput ((ObjectToTranslate) selection.getFirstElement ());
workbenchWindow.getActivePage ().openEditor (
myEditorInput,

TranslationEditor.ID,
true
);
}
catch (PartInitException myException) {
myException.printStackTrace();
}

}
}

public void selectionChanged (IWorkbenchPart aPart, ISelection
aSelection)
{
if (aSelection instanceof IStructuredSelection) {
selection = (IStructuredSelection) aSelection;
setEnabled ((selection.size () == 1) &&
(selection.getFirstElement () instanceof ObjectToTranslate));
}
else {
selection = null;
setEnabled (false);
}
}

I found the culprit line of code.

protected void addPages ()
{
try {
translationEditorPage = new TranslationEditorPage (this);
addPage (translationEditorPage, getEditorInput());
}
catch (PartInitException myPartInitException) {
myPartInitException.printStackTrace ();
}
}

Specifically:

addPage (translationEditorPage, getEditorInput());

It should have been

addPage (translationEditorPage);

Funny though is I was using another app (RCP) that I made which runs
perfectly fine against Eclipse 3.3.

But on Galileo, RAP, I get the StackOverFlow.

Anyway, hope this helps somebody else in the future.

Etienne,

I recently experienced myself some RCP/RAP functionality discrepancies.
This makes me wonder if a stack overflow would result also when running
on the 3.5 RCP.

If yes, then this is a RCP bug, but if not, then a RAP 1.2 one. In
either case, a great help would be for you to file a bug report on this.

Regards,
Robert
